Cassius is an ambitious and sly character, who is angry about the power that Caesar had. He plotted to get the power for himself, because he arrogantly believes himself to be superior and more qualified to lead. He is manipulative, easily tricking Brutus into allying with him by slipping letters of praise into his window so he will believe he is loved by the people of Rome. Cassius believes that once he has Brutus on his side, he will be able to defeat Caesar and "Shake him" (1.2.334) from his throne. His clear manipulation of Brutus shows that Cassius does not care for Brutus or his friendship, he has the singular goal of becoming the new emperor of Rome. Shakespeare uses Cassius words and tone to show his evil intentions. After he has overthrown Caesar, Cassius wants to have Brutus "Disposed" (1.2.323), showing that he has not sympathy or feelings of admiration for Brutus at all, he is only pretending.
